10 Best Image Resizer Tools
1. Free Image Resizer: BeFunky
BeFunky is a great free image resize tool because it offers a lot of options. You can choose basic photo resizing and editing for free. If you want more options, you can upgrade your account for a monthly fee. This will get you access to options like photo filters and effects, touchups, frames, text, and more.
With the free option, you can resize your image by width or height, or by percentage scale. For example, if you know you need your photo to be 500 pixels wide, you can type that into the “Width” field. It will automatically choose the height so that the image isn’t distorted.
If you want to choose width and height yourself, just uncheck the “Lock Aspect Ratio” box. Be careful, because this can make the photo quality worse when the ratio changes.
Best for: Quick and simple photo resizing.
2. Bulk Image Resizer: B.I.R.M.E
B.I.R.M.E. stands for “Batch Image Resizing Made Easy.” This bulk image resizer has two versions: version 1 and version 2, which is newer. Both versions can help you resize several images at one time, instead of doing them one by one.
You can also add a border to each photo. Just choose how many pixels thick you want it to be.
One of the best features of B.I.R.M.E. is that you can preview the photos before you’re done, so you know how they’ll look. This can make the editing process faster and easier.
Best for: Resizing multiple images at the same time.
3. Resize Image Online: Rszr
This tool offers an option that many free image resizer tools don’t offer. You can crop a certain part out of your image, and then resize it too. This can be helpful if there’s too much white space around a product, or if you want to remove a person from the side of a photo.
You can also rotate the image to the right or left.
Note: to use this free image resizer, you need to enable a Flash Player in your browser. If you don’t have one enabled already, Rszr will ask you automatically.
Best for: cropping, rotating, and resizing photos.
4. Resize Multiple Images: Online Image Resize
This simple image resizer tool is great if you find some online image resizers to be confusing or difficult to use. There’s just one option: choose one or more photos, and then choose the width that you want all of them to be. The minimum is 16 pixels and the maximum is 1024.
Online Image Resize will automatically change all photos to be that width. Then you have the option to edit individual files by cropping, rotating, mirroring, or resizing more. When you’re done, you can download them individually or all together in a ZIP file.
Best for: Simple image resizing.
5. Resize Images for Social Media: Social Image Resizer Tool
Social Image Resizer Tool is a brilliant tool for all your social media image needs. Once you upload your photo, there’s a dropdown menu where you can choose what you want to use the photo for.
Options include:
- Cover and profile photos for LinkedIn, Twitter, and Google
- Pinterest and Instagram thumbnails and Lightbox images
- YouTube channel art and custom video thumbnails
- And many more
You just select the option you want, and the tool will let you crop and resize your image until it fits the dimensions of your choice.
Note: the maximum file size is 2 MB. If your original photo is larger, you may want to use a different resizer or compression tool first to make it under 2 MB, then use this tool to make it the right size for social media. Keep reading for more info about compressor tools.
Best for: Resizing images for social media.
6. Free Image Resizer: Simple Image Resizer
They weren’t lying when they named it “Simple Image Resizer.” You can select your image, choose if you want to resize based on dimensions (pixels) or percentage, choose the pixels or percentage number, and then click Resize.
Be careful with the dimensions option, because it doesn’t offer the option to automatically keep the proportions. This might lead to a distorted or weird-looking final result.
You can only make a photo smaller, not larger. But it’s important to note that making an image larger will cause the quality to be worse. So you should try to avoid this anyway.
Note: this tool also allows you to convert images from different file sizes. For example, JPG to PNG.
Best for: Simple image resizing and converting images into different file types.
7. Resize Images For Social Media: Photo Resizer
Best Photo Editing App Mac
This tool is similar to Social Image Resizer Tool (#5 in this list), because it helps you resize images for certain social media uses like Facebook, Twitter, Google+, and Instagram. However, it has less options.
It also offers extra tools similar to Microsoft Paint. You can rotate or flip an image, as well as free draw on the photo or draw circles or rectangles. These can be helpful if you want to draw a visitor’s attention to a certain part of a photo. You can also add text, like a caption or headline.
The Sharpen option in the Tools dropdown menu can help make a blurry image look clearer, which can help with image quality.
Best for: Resizing images for social media.
8. Resize Multiple Images: I Love IMG
Another tool to resize multiple images, I Love IMG makes the process easy. Upload all of your images at once, then choose if you want to resize by pixels or percentage.
The By Pixels option offers a helpful feature, which is a checkbox that says “Do Not Enlarge If Smaller.” For example, say you want all photos to be 800 pixels wide. If some of your photos are 700 pixels wide, it won’t make them bigger. This prevents them from becoming blurry and pixelated, so you have high quality images.
Best for: Resizing multiple images at the same time.
9. Free Image Resizer: ResizePixel
This is another simple and clear-cut tool that also lets you resize images. Choose the width and height in pixels, then choose if you want the final image to be compressed without losing the quality, or resize the image in kilobytes or megabytes. You can also choose to convert the files to JPG, PNG, GIF, WEBP, TIFF, BMP or just keep them the same.
Keep in mind that the automatic compression mode will reduce the image size without visible loss of quality. If you need more control over the file size you can reduce the image in kilobytes or megabytes. It is worth mentioning that image size is important because heavy images can slow down your website’s loading time thus reducing the conversion rates.
Best for: Simple image resizing.
10. Bulk Image Resizer: Bulk Resize Photos
Bulk Resize is simple and easy to use. The menu is on the left side of the screen, and the screen will change based on your choice. Options include scale by percentage, longest side, width, height, and exact size.
Free App To Resize Photos
Longest side means you can choose a set amount of pixels for the longest side of each photo. For example, say you choose 800 pixels. Photos that are landscape/horizontal will have a new width of 800 pixels. Photos that are portrait/vertical will have a height of 800.
This option is helpful if your photos aren’t all the same layout.
Best for: Bulk image resizing.
How to Resize Image Without Losing Quality Online
When you use free image resizing tools, you might find that the quality of the image is worse. This can be seen when the photo becomes blurry, pixelated, or distorted. It’s important to make sure that tool you use doesn’t lower the image’s quality. This can harm your store’s performance.
Many of the free tools you can find online will make it a priority to keep high quality. This can be seen in some of the tools we discussed, which will ask you what quality you want your final image to be, on a scale of “low to high” or up to 100%.
For example, the free image resizer B.I.R.M.E. we discussed above has this “quality setting” option. You can choose up to 100%. We recommend this if the file isn’t too big.
You can also find image compressor tools online to help resize image without losing quality online. For example, the free image resizer toolsI Love IMG and Simple Image Resizer that we discussed above have the option to compress an image.
Optimizilla and Compressor.io are two other great online image compressor tools. Optimizilla lets you compress multiple images, while Compressor.io works one at a time.
